Cherry RedThe Moody Blues‘ Justin Hayward, Yes‘ Jon Anderson and Mick Fleetwood are among the many stars featured on Songwriter, a compilation of the work of French folk-rock musician Alan Simon that’s just been released as a two-CD set. The album, which previously was only available on vinyl, includes tracks from various albums by Simon, who is known for creating concept albums based on Celtic myths and history.

Among the other guest artists appearing on the Songwriter collection are late Asia frontman John Wetton, longtime Jethro Tull guitarist Martin Barre, ex-Fleetwood Mac guitarist Jeremy Spencer, Billy Preston, Midnight Oil, Alan Parsons, and various members of Supertramp.

“The 40 songs on the compilation are all personal selections from my rock operas and concept albums: Excalibur(the quadrilogy), Gaia, Anne de Bretagne, Tristan & Yseult, Captain Kid and various soundtracks,” Simon explains. “Some of these tracks fans may know already and other tracks offer a deeper insight into my work! Songwriter is a sentimental and personal collection which also includes a comic strip of my journey.”

Meanwhile, Simon will release the fourth installment album of his Celtic rock opera series Excalibur on November 3. Excalibur IV features contributions from Wetton, Barre, Supertramp’s John Helliwell and Jesse Siebenberg and many others. Simon is planning to mount a tour in support of the album in 2018.
